Cheap, N/A, Fast 7XX-??? for Racing or Whatever?
Hi all, first post, sorry if I'm doing it wrong.
This is my first foray into anything Volvo, and my first time seriously taking on a build, so try to be gentle, or don't, whatever.
The build will be for an ice racing series, so we'll be doing the necessary stripping and caging first, then trying to squeeze in whatever suspension refresh and engine work we can. The rules state that the latter must appear stock and no turbos are allowed. We're also mostly broke.
I have what I believe to be a '90 740GL sedan. I'm working on identifying further details but unfortunately right now as I post this I only have photos of the sticker on the timing cover (so I know it's a B230F, with a K on the far right side, likely original,) and the vehicle ID. It's an auto, but this might change.
Wanted to present ideas I have had to see if they make sense, or I'm out to lunch and my priorities are whack:
Thanks in advance!

Wanted to present ideas I have had to see if they make sense, or I'm out to lunch and my priorities are whack:
- Though well maintained, it's s-l-o-w. Particularly bad above 4k RPM and I'm reading that the "M" cam in this engine may be partially responsible. Used parts may be available nearby but TBD, so I'm wondering if there's a source I've missed for new camshafts for a Redblock (since IPD doesn't seem to stock an N/A cam.) Or will an adjustable gear + what's below more or less fix this for less cash? FWIW, emissions, mileage and "street drivability" are not concerns. Loud, rough and smoky is just fine.
- Seeing various tricks for for breathing (porting head/intake manifold, 960 throttle body, 2.5" straight pipes, etc.) and compression (thinner gasket, decking block/head,) but tough to quantify what I might actually gain, and potential pitfalls of such (what might I lose?)
- A/C is already gone, but removing power steering pump and adding an electric fan seem like no brainers, right?
- Does anything need to be done to the computer to support any of this?
Thanks in advance!
